how many ounces of pure water must be added to 75 ounce of a 20% salt solution to make a salt solution which is 15% salt?
:
Let x = amt of water to be added:
:
.20(75) = .15(75+x)
:
15 = 11.25 + .15x
:
15 - 11.25 = .15x
:
3.75 = .15x
:
x = 3.75/.15
:
x = 25 ounces of pure water to be added
:

Check solution using the salt content:
.20(75) = .15(75 + 25)
15 = 15
